HOUSE AND GARDEN 
July, 1911 
The Scotch grow to be deeply attached 
to these little dogs, and one man who owns 
several of them always has some story to 
tell of their intelligence. One of his dogs 
named Fiorag, which is Gaelic for squirrel, 
has a wise little trick which she plays when 
she wants to get a warm, cosy seat. She 
goes to the door and wags her tail as if 
she were begging to be let out, and when 
her master rises and goes to the door she 
darts past him and nestles down into the 
warm recesses of his vacated chair. 
They have tremendous endurance, these 
little dogs, and it seems almost impossible 
to tire them. They are not heavy eaters, 
and not at all particular, but are just wise, 
wholesome, healthy, fine little dogs. Real 
“doggie dogs,” as some one described 
them. G. A. 
The Woolly Aphis 
I HAVE discovered a new kind of pest on my 
young apple trees (now 4 years old) which 
I am not familiar with, and write to ask if 
you can tell me what it is and how to kill it. 
It appears on the branches, especially at the 
ends where they were pruned last season, in the 
form of a white, woolly substance and under 
the glass can be seen several grubs in each 
effected spot, which seem to come out of the 
wood itself. I have sprayed with arsenic and 
also petroleum emulsion, but without any effect. 
If you can give me any information on the 
subject same will be greatly appreciated.

In reply to your query, we would say 
that from the descriptions given in the let¬ 
ter the pest is probably the Wooly Aphis 
of the Apple. This insect is interesting be¬ 
cause it has two distinct forms, one of 
which is found on the branches above 
ground and the other below the surface of 
the ground upon the roots. The root form 
is much the more serious one of the two. 
It lives upon the roots, sucking the juices 
from them and stimulating the tissues to 
produce swellings or galls. The roots final¬ 
ly decay, break away from the tree and 
eventually the tree dies as a result of the 
presence of this root louse. When this 
pest becomes well established in a young 
orchard it is exceedingly injurious. 
Very good results have been obtained 
by hoeing away the soil in a circle about 
the tree to the depth of 3 or 4 inches. The 
diameter of the circle will vary, depend¬ 
ing upon the size of the tree. It should be 
at least 2 to 3 feet in diameter for trees 
10 to 12 years old. The ground in the 
circle should be soaked with a 15% solu¬ 
tion of kerosene emulsion, using 2 or 3 
gallons or even more to the tree. This 
material will penetrate the soil and kill 
great numbers of the aphids. In some 
cases it has held the aphis in check very 
effectually. After the emulsion is applied 
the earth should be replaced. This should 
be done only while the tree is in leaf; if 
done while the tree is dormant the roots 
are apt to be injured by the kerosene. 
The branch form can be controlled by 
spraying with a 10% solution of kerosene 
emulsion or with whale-oil soap; one 
pound to 5 or 6 gallons of water.
